Summary of the invention:
Task of the present utility model provides a kind of mode of motor output slow speed of revolution and big torque of utilizing and drives the keying of elevator cab door to reduce the control setup that the elevator cab door opens and closes that is used for of its making and use cost.
The utility model proposed be used for control setup that elevator cab door opens and closes comprise be installed in the lift car doorframe respectively or near it both sides and by the directly actuated driving wheel of motor with by endless belt and driving wheel bonded assembly flower wheel, and be arranged on this motor input end and be provided with the servo-driver that is used for the control motor output signal.
Described servo-driver comprises the feedback unit that is used to detect motor speed and armature current that is arranged on motor output end; And main control unit, the expectation value of this predefined motor speed of main control unit internal memory contain and torque and position is used to receive the detection data of described feedback unit and compares motor is sent the comparing unit of control command with described expectation value; And by the output signal of main control unit performance element control and that be applied to the motor input end.
Described feedback unit comprises the velocity feedback assembly that is used to detect the current feedback of armature current and is used to detect motor speed.
Described current feedback can constitute by having the current sensor that self has amplification and analog-digital conversion function, perhaps by sample resistance and amplifier that the current signal that this sample resistance takes out is amplified, and the A and D converter that the current analog signal after amplifying converts digital signal to constituted.Described velocity feedback assembly is by data preprocessing module constitutes in the described main control unit in order to the coder of periodically described motor output speed being sampled with entering data into of joining of this coder mouth.
Described performance element have power drive unit and drive by this power drive unit and be applied to being used on the motor and handle the inverter circuit of motor speed.
Be provided with the fuzzy control unit in the described main control unit and the control unit of adjusting certainly, after the feedback signal of main control unit inbound pacing output valve and by comparing unit and desired speed output valve, compare, differ predetermined value by the adjustment of fuzzy control unit as both, and it differs less predetermined value by the controller adjustment of adjusting certainly.
The servo-driver that the control setup that is used for the keying of elevator cab door that the utility model proposed adopts can make motor output slow speed of revolution and big torque, and rotating speed and torque, and parameter such as position can be from setting, so, directly drive the door action of bridge railway carriage or compartment with this motor and become possibility, promptly omit many parts such as speed reduction gearing and driving device, its structure is become simply, greatly reduced the use and the cost of manufacture of elevator again.
